Honestly, I'd be more interested in knowing why they chose SVN over the many options out there, and furthermore which options they considered in the first place. I hear about CVS, perforce, subversion, GIT, and mercurial all the time, but there are yet more options out there. For example, I recently discovered darcs, which I like as it happens to think about revisions the way I do (patches.) They all have their own qualities, and the more familiar the differences are, the easier it is to decide which tool matches the project best.
